Larry,
Again I don't know anything about part compatibility, so you will need to talk to a good trany builder first, but here are some options. All speeds are at 7000 on a 23 inch wheel.
option 1
A US gvr4 trans with an evo/rs secondary (this will require a $500 rear ring and pinion or some luck and generosity on cheeky's behalf)
1st 30.99
2nd 52.37
3rd 79.09
4th 105.86
5th 132.41
not that much gain but it will definitely work.
option 2
A US gvr4 trany with a ggsx primary. I have no idea if these parts are compatible but they are parts available in the US.
1st 25.91
2nd 43.79
3rd 66.14
4th 88.53
5th 110.73
probably much closer to what you are looking for
option 3
A US gvr4 trany with a ggsx primary and an evo/rs secondary. This is probably the least economical way of doing it, if it would even work.
1st 23.52
2nd 39.74
3rd 60.02
4th 80.34
5th 100.49
option 4
A evo/rs trany with a ggsx primary.
1st 26.03
2nd 41.83
3rd 57.69
4th 77.64
5th 108.47
Again all of this is just a numbers game. I know nothing about part compatibility. If the gears themselves can be swapped (like 5th for example) there would be quite a few more options.
